Bearing Load at 63% bearing check station uptime: a worked example

This worked example runs the bearing load numbers for a tougher week than the baseline: 63% bearing check station uptime instead of the typical 88%. Estimate accepted bearing load checks from checks per test cycle, available cycles, uptime, and first-pass bearing inspection yield.

The inputs for this scenario

  • Bearing checks per cycle: 2 checks / cycle (held at the documented default)
  • Available bearing check cycles: 30 cycles (held at the documented default)
  • Bearing check station uptime: 63 % (the input this scenario stresses; the baseline uses 88)
  • First-pass bearing check yield: 94 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross bearing check capacity = bearing checks per cycle × available bearing check cycles.
  • Accepted bearing check capacity works out to 35.53 loads at these inputs, and this is the headline figure for the scenario.
  • Gross bearing check capacity works out to 60 loads at these inputs.
  • Bearing check station downtime loss works out to 22.2 loads at these inputs.
  • First-pass bearing check yield loss works out to 2.27 loads at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where bearing check station uptime sits at 88% and the headline result is 49.63 loads, this scenario comes in 28.41% below the baseline at 35.53 loads.
  • Use it when planning or load-balancing the bearing-inspection station on a fan or blower production line. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Accepted bearing check capacity: 35.53 loads (headline result)
  • Gross bearing check capacity: 60 loads
  • Bearing check station downtime loss: 22.2 loads
  • First-pass bearing check yield loss: 2.27 loads
